Hi guys ,
Please help me
....my question is that why the cut off frequency of an RC circuit depends upon 'R'...according to formula
f = 1/ 2pi R C... Since as we all know that capacitor is frequency selective..not resistance ...so the cutoff frequency should be solely dependent on capacitance...as the resistance is indifferent to the frequency...also as per formula resistance is having its contribution ...why and how?
thanks
